The Zenit 6 is a 35 mm SLR camera with a leaf shutter in the body, made by KMZ in the 1960s. Nathan Dayton states that the camera is exactly like the Zenit 4, produced at the same time, but was supplied with the Rubin-1 37-80 mm f/2.8 zoom lens as standard, instead of the Vega-3 50 mm lens. G. Abramov states that the lens is a slightly-modified copy of the Voigtländer Zoomar.
